01
Pick a topic
Choose one of the Electrotechnology topics above or type your own, then pick your state. WACE, VCE, HSC, QCE and SACE each word their questions differently, and the paper follows yours.
02
Attempt it yourself
Exam-style questions with the mark allocation showing, so you know how much to write. You answer them — nothing is handed to you.
Two resistors of 12 Ω and 6 Ω are connected in parallel across a 24 V supply. Calculate the total resistance, total current and the current through each resistor. (6 marks)
03
Get it marked
Your answer comes back marked criterion by criterion in seconds — what you earned, what you half-earned, and what the examiner never saw.
4/6 · ✓ Combines parallel resistances using the reciprocal rule
04
Fix the gap
The topics you keep losing marks on come back around in your review until they're strong. That's the whole point.

Marked in seconds
✓ Combines parallel resistances using the reciprocal rule
✓ Calculates total current from the supply voltage
△ Recognises the branch currents must sum to the total
✕ Applies the full 24 V across each branch — 2 A and 4 A, not an even split
